hi all, anybody have an idea where i can find that libtli library which is required by ZSybaseDA and appearently isn't part of sybase open client for linux. i really want to try out tying sybase for linux into zope and would greatly appreciate if anybody could help me solve this problem. regards, webman --------------------------------------------------------------------------- webman | _ beehive GmbH | ASCII ribbon campaign ( ) berlin, Germany | - against HTML email X http://www.beehive.de | & vcards / \

Re: [Zope] RE: sendmail and variable mailto
by Jeffrey P Shell 14 Feb '99

> This won't do. I really need to be able to send mail using only the > received variable, and no folder properties; at least no dynamic ones. the REQUEST variable has the attribute 'form', which contains only the passed-in values in a form. For example,  will _only_ get the email address from the form. I don't understand why you're trying to set the folders property if it constantly gets overwritten with each request. In any case, if two people access a page at the same time and that page modifies a property, the transaction (the entire process from when Zope recieves the REQUEST to when it sends out RESPONSE) is atomic. That is, if Person A hits first, all of his transactions will be carried out and used beforer Person B can. Unless you're using ZServer, Zope really only handles one request at a time. In regards to what I think you're trying to do with the sendmail tag, you don't have to use the 'mailto' and 'mailfrom' parameters. The only parameter you really need is the ID of the mailhost or the IP address of the SMTP host. To do dynamic to's and from's and even subjects, do the following:  to:  from:  subject: congratulations on your furby addiction! message  The sendmail tag process all the headers and uses the "to" and "from" headers evaluated values if mailto and/or mailfrom aren't set. If mailto and mailfrom are used, they don't necessarily show up in the message when its recieved as the mailto and mailfrom values are used to talk with SMTP. It's important to note that the headers and the body of the message must be seperated by a blank line. You can use any header in the header area you wish (like x-mailer: Zope_Is_King 1.10), Zope only cares about the to and from values. And again, only if the mailto/mailfrom parameters aren't in the tag itself. The code in the sendmail tag is rather old and we're open to new patches/mods people make (like using SMTP lib!). The mailto/mailfrom/subject parameters currently only evaluate their values as strings and don't look them up from the namespace. .jPS | jeffrey(a)digicool.com | http://www.zope.org/

RE: sendmail and variable mailto

Well, I see in the earlier 'Hiding Products' discussion how to set folder properties. But that makes me wonder... What happens when two people hit my page at the same time? Each enters their data, including an email, and reach the response page at about the same time. The contents of the pages are uniquely rendered, but surely their interactions with folder properties could cause some weird overlap, like this: A requests the page. B requests the page. Zope starts processing A's page. Zope sets the folder attribute based on A's email address Zope starts processing B's page. Zope sets the folder attribute based on B's email address Zope sends mail for A to current folder address - which is B's address. Zope sends mail for B to current folder address - which is B's address. A gets no response. B gets two responses. This won't do. I really need to be able to send mail using only the received variable, and no folder properties; at least no dynamic ones. Please help.

sendmail and variable mailto
by Shaw, Howard 13 Feb '99

13 Feb '99

This seems intuitively obvious... it just doesn't work...   Nothing much.   where home_emails is a variable from a form. I tried a test using   Nothing much.   and   Nothing much.   Please help. I really need to be able to selectively send mail to either home_emails or b_emails or neither, depending on which actually contains a value. If I can't include a variable as a mailto, can I set the folder attribute 'mailto' from within the script on the basis of the same selection, then use sendmail with on mailto? Will it find it then? The example in the DTML User's Guide implies it would, but I don't know how to set the folder attributes dynamically.

RE: [Zope] Shattered dreams... And glibc

Well, after a couple of hours of playing around with it and no crashes, I have connected the Zope driven database I was working on into our website. Hopefully, the changes I have made have fixed the problem. But I have another question... I am using as a mailhost my NT Exchange server... I am not sure whether the mailhost connection works or not. If the mailhost fails to work, where and how would the system notify me of this? Would it show up as a comment in the source of the viewed page, or in a log file, or where?

Installation on Solaris
by Dick Weisinger 13 Feb '99

13 Feb '99

Hi, I've helped convince the people at nexusweb to become a Zope ISP. They're pretty friendly in responding to me, most ISPs that I talked with flatly refused to have anything to do with Zope. But it looks like they're having problems getting it up and running on a Solaris machine. Any pointers someone can pass their way in the installation? Not exactly sure what the problem is. Thanks Dick Weisinger

I'm confused. Are you saying that you have a working setup that, asside from having ZopeHTTPServer die, is not having problems? How does this relate to the broken site. What I'm saying, is that I had a working setup; subsequently it developed a periodic death syndrome; then finally cratered completely after this wierd session problem. I presumed a connection, with no evidence, simply because it seems logical to me from the description I've read of the Bobo database, that the Zope server being cut off while accessing the file might leave the database in an uncertain state. The scenario I pictured was one where some portion of the basic database structure was corrupted, but the region internal to the session was not. Work within the session went fine, until the save, where it attempted to access the corrupt portion, failed, rolled back the changes, but was not able to 'undo' the session. This fits your general documentation, which implies that while individual changes can be individually undone, the application of a session can only be undone in the sense of a complete removal, and not of a restoration of the session to its prior state. Subsequent to the session difficulty, I started editing in the open. I only managed to touch four or five files before the database died and then refused to restart, which makes me think that I then manipulated the damaged region in such a way as to cause damage to the structural information, whereas before the damage was to the internals of individual items. Of course, all of this is complete guesswork. I never saw any useful log message other than the final message about a corrupt record. Therefore the fact that my ZopeHTTPServer is periodically dying implies that a similar crash lurks in my future. The reason I was unsure which you wanted, is that my theories imply that this working DB may contain information about the cause of the crash, while the other DB is completely inaccessible, so far as I can tell. Of course, I realize that working more directly with Bobo, one might be able to extract data more effectively than through Zope, which of course has a greater set of dependencies. For starters, please send the var directory containing the non-working Data.bbb files as a gzipped tar file. It is included. > I assume you don't want these > mailed to > the list; Right.

When I moved the non-working installation to a different directory, and installed a fresh copy of the binary package, I noticed that the first spontaneous crash did not come until after I installed the MySQLDA, even though I spent at least two hours rebuilding the links between a separate portion of the Zope site and my original site. (Using it as a replacement mirror.) The recurrent death returned during my rebuilding of the database using portion of the site. BTW, this is using the Zope internal version of Python with MySQLModule.so compiled from the source obtained with MySQLDA. Did it stop dying? When?

Hi Howard, I know you have been exchanging mail with Mike. I'd like to ask some additional questions. Is Zope installed on a local file system? NFS? Zope is installed on the local filesystem. Have you just started using Zope? Or have you been using Zope for a while without problems? I started using Zope fairly recently, and had only gone so far as to make it a mirror of my pre-existing site using fsimport. Can you take MySQL out of this mix for a while to see if it has any effect? Are there any other products installed that are not part of the Zope distribution? I can say that having just reinstalled the zope binary distro, I saw no regular stoppage of the zope server until after I reinstalled the ZMySQLDA and connected to the database. I have not manually installed any other products, though I did install the external method 'fsimport'. Are you running on your own machine, or on an ISP? This is running on a linux box in my care at my work. Are you using PCGI and Apache? Or ZopeHTTPServer? I am using ZopeHTTPServer, however, Apache is also running on the same machine, serving a web site containing, amongst other things, a PHP3 based database front end that also connects to MySQL, though to a different database. It would also be interesting to us to see your database files. Would you mind sending them to us (as an attached gzipped tar ball or Zip file)? I assume you mean the Data.BBB* files. Do you want the files from the current working setup (which is exhibiting the recurrent loss of Zope with no messages) or the non-working Data.BBB, or both? I assume you don't want these mailed to the list; should I send them to your personal account? The problems you are reporting are very odd. Needless to say, we don't see them here, so any info you give would be very helpfull. Please feel free to call me at the number below if you're interested in brainstorming this. I am very interested in determining the cause of and solution for this problem, especially since it was, in my opinion, related to the recurrent death of the ZopeHTTPServer, which has returned. Since I believe it to be only a matter of time until it dies again, I am keeping multiple backups of the Data.BBB* files. Are there any other data files I should be aware of, for purposes of backup, or do the Data.BBB files cover it?

Just to let anyone who was concerned with my case that the pressure is off for the moment. I have succeeded in re-achieving the status of the Zope database prior to its crash, and moving past. I remain impressed by the system's ease of programming. I had previously implemented portions of these systems in NeoWebScript and PHP3, and it compares favorably with both. (Well, in point of fact, it is far out of NeoWebScript's league, since said lingo is a rotten excuse for web programming. Apparently NeoSoft suffers from the NIH syndrome, which is sad, since I have met some of their techs, and they're generally pretty froody fellows.) However, any advice that anyone can offer regarding how to increase stability, such as examples of particularly stable configurations and what setup was gone through to attain them, would be greatly appreciated.
